Humour and Jokes / Re: 9001 signs you're addicted to calcs and Omni
« on: March 17, 2017, 02:41:06 am »
7633: You post after a year of inactivity just to remind it's been 7 years you joined this site
7634: You think time goes fast
7635: Do we really have 7635 signs you're addicted to calcs in this thread? Come on, 9001, you can do it.
7636: You never really left the community since the last 7 years, with a total post count probably close to 10000 now
7637: And you'll probably never leave either
7638: And even though you left Omni to help founding another forum due to reasons, you still think Omnimaga will live forever.
7639: Long live Omnimaga.

Introduce Yourself! / Hello again?

Did you missed me? Well, here I am, again. I guess. Also as of a few minutes ago it's been 6 years I'm here it's been a while? Well.

Anyway, nothing new, still in college and stuff like that, but I moved in town now. Which is kinda fun.

Well, see ya again later. Hopefully.

*disappears into his forum that totally isn't competing to Omni, I swear*

I guess SpiroH have a point. It's no longer what it was a few years ago. People probably have other stuff to do in class besides playing with their calc nowadays.

Ah yeah, I saw that one, well at least te first episode, isn't it that one the protagonists are in a glasses club and try to invent some fancy x-ray pair of glasses that backfires on them each time?

I'm watching Watamote, it's pretty fun.

Eh, sorry for stealing your activity >.> JK, I don't believe it's the only reason, as we founded CodeWalrus Omni was already starting to be the shadow of itself, which is kind of why we founded it in the first place...

I do believe a good spring cleaning should be done, we need some changes here, a contest would really help a lot.

Anyway, know that I and the other CW staff would definitely like some activity here (or at least this forum to not die) and support those ideas.

No one attempted anything on any of my accounts as far as I know other than the usual "there was security breaches on some other website that isn't ours and we think your account may be compromised so we've reset your password" (last one in date was Netflix btw, got one on Patreon and Adobe too, these breaches seems to be everywhere). Thankfully, nothing happened on CodeWalrus as the attacker could easily have tried there a well. Anyway, if you guys know the IP of the offender, please tell me so I can check on my side.

Introducing a new series of contests on CodeWalrus: the CWick Contests. The idea is simple: I give you a topic or a constraint (like this week's 140 characters) and you try to make the best one!

This week, the constraint is to make something fun in 140 characters.

It's my birthday! Or yesterday, depending of the time zone. I'm late.

I wrote the topic at 4am, was too tired to do a fancy post.

Can we have the first few bytes of expected output to check our work?
Here's the first 64 bytes (0.008 seconds) of output of a script I wrote, piped through od -t u1.

0000000 127 170 208 237 252 253 239 211 174 131  88  49  19   3   1  13
0000020  40  76 119 163 202 232 250 254 242 217 181 139  95  55  24   5
0000040   0  10  34  69 111 155 195 228 248 254 246 223 188 147 103  62
0000060  29   7   0   7  29  62 103 147 188 223 246 254 248 228 195 155

Of course, your mileage may vary.

May we start the sine wave at some point other than 128?
Of course. It does not matter anyway, it's cyclic. You probably even can use cos().

May we truncate instead of round?
Of course. That's what I did as well.

Hey, it's me again, Juju, hosting the eighth iteration of Code Golf: The Reboot. This week, the output will be... sound. Yep, you heard right. Pun intended.

The assignment today is a simple A4 sine wave, sample rate of 8000 Hz, in raw wave format. But first, you'll want to understand at least a little how to make one. First, know you'll have to output 8000 bytes to make one second, but you don't have to output all that in exactly one second. To make a simple A4 (frequency of 440 Hz), look at the graph for sin(x). Map the y from [-1,1] to [0,255] (don't forget to round it to remove the decimals!) and try to fit the wave you get ([0,2π[) 440 times in those 8000 bytes. Then just output the bytes you just generated, no header or anything. On calc, if you can output those bytes through the link port with the timing, that would be great (no Freq(), you Axe people!), otherwise, you can just output a list with the 999 first numbers you get (makes for about 1/8 of a second) or an infinite loop that disps the numbers (if you output on screen, you don't need the timing), or whatever the easiest for you. On PC, you can output the raw bytes in an infinite loop or the 8000 first ones (makes for one second) so I can pipe them through aplay.

tl;dr you have to output a very specific sin() function with specific parameters. Should be simple enough.

The rules are still the same, if you have any questions, please ask. Have fun!

@3298 - SysRPL - 53 bytes

Well, according to the OP that should be my turn, right?

That sounds fun. So who's doing it Monday?

I also have one ready, but I'm not sure if it can be doable on calc. You have to send a bunch of bytes via the link port, although I could always make them save it to a string/appvar/screen/etc.

Heard @c4ooo won't be able to host either, so guess it'll be my turn? Well I'm ready.
